Yes they are. It's not the OS that matters but the architecture of the 
libdb4.so file.
It is still a good idea not to use Berkeley DB for real important data. 
Here at our university's cyrus we are using Berkeley for the duplicate 
delivery and the tls databases - both of them are easily set to zero in 
case of problems without deep impact on the functionality (in case the 
delivery db crashes users can get some mails two times (doubling), in 
the latter case (tls db crash) a returning client has to re-initiate a 
TLS handshake including key exchange).
